GPT-5

OpenAI's flagship API model for 2025, built for advanced reasoning, coding, and agentic tasks. Excels at producing high-quality code, following long chains of tool calls, and delivering expert-level analysis across domains. Supports 400K context window, steerability, structured outputs, and new features like 'minimal' reasoning and verbosity control.

GPT-5 Mini

A faster, more cost-efficient version of GPT-5 built for well-defined tasks. Great for structured prompting, high-frequency applications, and fast iteration. Supports tool use and reasoning, with 400K context and strong performance across domains.

GPT-5 Nano

The fastest and most affordable version of GPT-5, optimized for summarization, classification, and simple task automation. Ideal for high-throughput and cost-sensitive applications with strong reasoning capabilities in constrained tasks.

GPT-4.1

OpenAI's flagship API model for 2025, excelling at advanced programming, large datasets, and complex instructions. Outstanding for code-heavy and technical projects, with a massive context window and top-tier coding/instruction-following performance.

GPT-4.1 Mini

Balanced speed, cost, and intelligence. Matches or exceeds GPT-4o in many benchmarks, with much lower latency and cost. Ideal for high-frequency, cost-sensitive, or latency-critical applications.

GPT-4.1 Nano

Fastest and most affordable in the 4.1 family, designed for simple, high-frequency, or edge tasks, while retaining the large context window.

o1

OpenAI's previous top reasoning model, now superseded by o3. Still strong at structured reasoning, science, planning, and math.

o3 Mini
